What Do You Do In High Pressure Situations Involving Just A Few Words Or One Sentence?

What Do You Do In High Pressure Situations Involving Just A Few Words Or One Sentence? So this is a pretty unique problem I have and I don't know if anyone else here also has it. As a stutterer, I actually sometimes find it harder to say one word (or a short sentence) than walking up to someone and having a long conversation with them. I stutter during conversations too, but there's less pressure there because I don't know what I'm going to say during the conversation. During a conversation, I am going with an empty mind and improvising on the spot. When I improvise, I stutter less because there isn't as much anxiety, force and pressure in enunciating since my mind doesn't have enough time to worry about the words. However in situations where I already know what to say, like asking a cop on the street " What time is it? '' or asking a post office worker '' I'm here to pick up my package '', that's when I feel an ENORMOUS amount of fear and anxiety in me building up, and when I open my mouth to talk, I feel a block inside and have a hard time getting through it. Its much harder than having a conversation with someone. And I find that the more of a time gap there is between me planning on saying it and actually saying it, the worse it gets. Like if I'm walking up to the post office, I can feel the fear building up. The longer the walk is, the more fear builds up and the harder it is to say the word. Whereas if I was already at the post office (coincidentally) and I suddenly remembered that I have to pick up a package, I can instantly tell the guy '' Hey I have a package to pick up ''. I would still stutter but it would be much easier to say it because my mind hasn't had the time to build up anxiety. How do you navigate through situations like this? I know an obvious solution would be '' Just don't worry '', but you can't just block out stuff like that. Are there some techniques you can use in situations like this?
